Human Strength Limits: arm_hand_strength
Human force capability data from MIL-STD-1472F for equipment and control design. Covers maximum design weight limits for lift and carry tasks (Tables XVII), horizontal push/pull force limits by traction condition (Table XVIII), and static muscle strength at 5th/95th percentile for male and female populations by posture, height, and hand configuration (Table XIX). Also includes arm/hand strength reference values from Figure 23 (arm pull/push at elbow angles, hand grip, thumb-finger tip grip). Used for equipment design weight compliance, control force limit verification, and manual materials handling assessments per MIL-STD-1472F paragraphs 5.9 and 5.9.2.
